Hi, i want to know how to manage files, i understand all about files managing in C on a PC, here is my problem: I got a data stream captured with A GPIO port, that stream is an image, and i want to save it to an USB stick, so it's necesary load all the image in RAM (the image data expected doesn't fit in the RAM) or i can write byte to byte received to the file whitout loading all the data in RAM?
